Product overview
Carbide ball needs excellent corrosion & erosion resistance, which are majorly used to the stationary and roving unidirectional valve in various tube and rod defueling oil pump.
Cobalt bonded, Nickel bonded and Nickel-Titanium bonded grads are available for highly corrosive and serve service applications. The unique property with good balance of toughness and hardness, cemented carbide valve ball achieves high pumping effect and a long pump check cycle.
